Abstract

Embodiments operating shared peripherals in a hybrid computing system are described. Embodiments control a shared wireless antenna variously between a primary system and a secondary system, where the secondary system is detachable from the primary system and operates as an independent computing device in the disconnected state, while operating as a display device in the connected state.

Claims (30)

1. An apparatus comprising:

a base device having one or more processors therein, the base device having a first operating system; and

a display device having one or more processors and a shared wireless antenna therein, the display device being detachably connected to the base device, the display device having a second operating system;

wherein the based device is configured to control the shared wireless antenna when the display device is connected to the base device;

the apparatus further comprising a controller and a first radio housed in the base device and a second radio housed in the display device;

wherein the controller is configured to control the first radio such that the first radio is powered on when the display device is attached to the base device.

2. The apparatus according to claim 1 , wherein the display device is configured to control the shared wireless antenna when the display device is not connected to the base device.

3. The apparatus according to claim 1 , wherein the first operating system of the base device is configured to output data for display to the display device when the display device is connected to the base device.

4. The apparatus according to claim 1 , wherein the second radio is controlled such that the second radio is not powered on while the display device is attached to the base device.

5. The apparatus according to claim 1 , wherein the controller is further configured to, responsive to the display device being attached to the base device, ensure that the second radio is powered down prior to powering on the first radio device.

6. The apparatus according to claim 1 , wherein the display device is a tablet computing device.

7. The apparatus according to claim 6 , wherein the display device is configured to operate the shared wireless antenna to transmit and receive data when the display device is disconnected from the base device.

8. A method comprising:

sharing a wireless antenna between: a base device having one or more processors and a first operating system; and a display device having one or more processors, the shared wireless antenna, and a second operating system; and

switching control of the shared wireless antenna from the display device to the base device responsive to connecting the display device to the base device;

wherein the base device further comprises a controller and a first radio and further wherein the display device further comprises a second radio; and

wherein the controller controls the first radio such that the first radio is powered on when the display device is connected to the base device.

9. The method according to claim 8 , further comprising controlling the shared wireless antenna with the display device when the display device is not connected to the base device.

10. The method according to claim 8 , wherein the first operating system of the base device is configured to output data for display to the display device when the display device is connected to the base device.

11. The method according to claim 8 , wherein the controller controls the second radio such that the second radio is not powered on while the display device is connected to the base device.

12. The method according to claim 8 , wherein the controller ensures, responsive to the display device being connected to the base device, that the second radio is powered down prior to powering on the first radio device.

13. The method according to claim 8 , wherein the display device operates as a tablet computing device responsive to detaching from the base device.

14. The method according to claim 8 , wherein the display device operates the shared wireless antenna to transmit and receive data when the display device is disconnected from the base device.

15. A computer program product comprising:

a non-transitory computer readable storage device having computer readable program code embodied therewith, the computer readable program code comprising:

computer readable program code configured to share a wireless antenna between:

a base device having one or more processors and a first operating system; and a display device having one or more processors, the shared wireless antenna, and a second operating system;

computer readable program code configured to switch control of the shared wireless antenna from the display device to the base device responsive to connecting the display device to the base device;

wherein the base device further comprises a controller and a first radio and further wherein the display device further comprises a second radio; and

computer readable program code configured to operate the controller to control the first radio such that the first radio is powered on when the display device is connected to the base device.
